Shrink SQL Server 2008 Database Log File Script

I found this script to shrink the database log file in a SQL Server 2008 database. This procedure has changed, since the BACKUP command does not work the same way as previous versions.

Use DatabaseName
GO
Alter Database DatabaseName Set Recovery Simple
GO
Alter Database DatabaseName Set Recovery Full
GO
DBCC SHRINKFILE ('LogFileName', 1)
GO
